roam; WHOM IT MAY concerts:

Be it known that I, Jonu B. Srouun, of the city, county, and State of New York, have invented a new and useful Improvement in Ballastiug vesselsg and Ido herehydecl are that the following is afnll', clear, and era-ct description-thereof, which will enable others skilled in the art to. make and use the same, reference being had to the accompanying drawings, forminggpart of this specification, in which- 1 Figure 1 is a vertical longitudinal section of a vessel, illustrating. several modes of carrying my inventionllltOsPl'fiGllCtll use, taken through the liner: fig. 2.

Figure is a detail cross-sectiqnof the same, takenthrough the line y y, fig, 1. Figure 3 is a detail sectional view, taken through the line 2 z, fig. 1.

Similar letters of reference indicate corresponding parts.

M'y invention has for its object'to furnish an improved modeoitemporarily ballasting a vessel when neces- Y sary, by lowering weights into the water, so as to prevent the rolling or ca'psizing of said vessel;" and it consists in-temporarily ballasting the vessel, by a weight or weights pivoted to, or otherwise connected with, the hull of said vessel, in such a manner that they may be quickly and conveniently lowered into the water when required, and readilyruised again whennot required. a

I A represents the hull ofe vessel B is a weightmad of a size andw'eight varying-with the size and form of the vessel to which it is attached. C are rodsri gidly and securely attached to the weight B, and extending bacl: with a. curve corresponding withthe form of the vessel. The ends of the rods 0 m pivoted to the middle of the upper part of the-vessels ball by bolts, or other convenient means, so that the weight B may be raised and lowered freely. D is a rope'or chain, the endo? which is securely attached-to the weight B, which passes np-over a pulley or pulleys E, attached to the upper part of the bow of "the vessel, and thence back to some convenient place, where its free end is secured to a belaying-cleat, belaying-pin, or in. some other convenient manner. F is a weight, which may be lowereda'nd raisedrertically, and-the lower part or which is so formedthat when rais'ed into-and secured in the recess G, formed for its reception,- its lower outside surface may conform to and coincide with the form of the'vessels bottom, so' as when raised to" ofl'er no obstruction to the vessels movement through the water. The recess G," for the reception of the weight F, is formed of metal or other suitable material, set and secured in a holecut through the bottom of the vessel, the part of the vessel weakened by cuttlngsaid hole being strengthened by metallic flanges or plates, H, formed upon or firmly attached to saidmetallic recess,'aud securelybolted to the-vessels bottom, as shown iu-figs. 1 and 2. From the top plate of the recess G'to the deck, or some other convenient part of the vesselfextends a well or oblong tube, S,,havi-ng pipes or tubes 'formed in itsnarrower sides, said tubes being slotted upon their inner sides, from their upper ends 'hearl'y to their lower ends. To the upper side of the weight Fare securely attached the lower ends of two rods, I, the upper ends of which are connected by ashort cross-bar, J, whichtmoves up and down as the weight'F is being raised or lowered through'the slotted sides of the tubes in the wells The upper ends of the rods I, just below the cross-bar J, are enlarged, or made cone-shaped,to fit into thecontracted or c'onical-shaped lower parts of the tubes in the well S, through whieh'the said rods I movenp and down. Tothe ceutralpart of the crossbar is'attached a rope or chain, K, which passes over a pulley attached to some suitablesupport, above the upper end of the well or tube S, and-its free end is secured to a. belaying-cleat, belaying-piu, or tosorne convenient support. Lisa" weight formed upon o-r,rigid ly attached to th'e end of an arm, M, which fits into and is pivoted iua recess formed in the bottom of the vessel, in a manner somewhat similar to a. pivoted centre-board; The part of the vessel weakened by cutting out the hole'for the recess, to receive the weightL and arm M, is

strengthened by flanges N, formed'upon or firmly'attachcd to said recess, andsecurely bolted to the bottom timbers of the vessel. O is a rope or chain, the end of which is attached to the weight L, and which passes up through the tube P, passes over a pulley, attached to sornesuitablesupport above the upper end of the tube P, and its free end is secured to a Delaying-clout, belayiug-pin, or in some other convenient manner.
